Re: any maker planning a modern p-8 Poseidon
NG certainly seem to have the resources to do this, and given Gemini's production of AF1 with all its aerials and little pieces, this should be very possible. But the test engine 757 was a much simpler task, only needing two additional small pieces to the standard fuselage. The Poseidon would need a new wing, but given the fact that NG and JC both produced the Beluga (with only 2 being manufactured), it is a matter of time before we see it. I would take NG's rendition over JC/GJ sight unseen any day.
